Face recognition: The next big tech leap

You open your laptop lid and instantaneously the operating system recognizes you and logs you in. Or, just as you enter your office, the camera over the door takes a look at you and opens the door after seeing you are an employee.

These may not be popular, but the face-recognition technology, on which they are based, is not a futuristic concept either. Though not widely publicised, engineers have been working on it for long.

Internet companies like Facebook and Googleare trying to use the technology to make it more user-friendly. Success has been mixed, and compounded by privacy issues. In August this year, Facebook, in an update to its data-use policy, said it was planning to include most of the 1-billion plus profile photos into their facial recognition database.

Its intent is to speed up the process of tagging friends and acquaintances who appear in photos posted on the network. Now, the technology automatically identifies faces in newly uploaded photos by comparing them only to previous snapshots in which users were tagged. And for good measure, Facebook users have the option to remove tags identifying them in photos posted by others. But the new move drew the attention of US officials who are trying to determine if it's in violation of a 2011 agreement with federal regulators.

In June last year, Facebook acquired a facerecognition technology firm in Israel, Face.com. However, after privacy concerns, Face.com's API, which could identify people based on digital photos , was shut down. Later, a US startup LambdaLabs came out with an open-source API. The company's co-founder Stephen Balaban told Tech-Crunch that the API would be available to interested developers working on Google Glass. Google later announced that it would not allow any face-recognition features on Glass.

But that has not stopped research. In June, TechCrunch reported that another company, Orbeus , was developing a face-recognition technology that takes adequate care of privacy issues.

While not revealing the person's identity, it can recognize gender and emotions, and vaguely even say how beautiful a person is. Stating that its API doesn't violate Google's updated Glass policies, Orbeus CEO Ning Xu told TechCrunch, "Even without facial recognition, we can do a lot of things with your face, without revealing your identity."

Thanks to privacy concerns, the technology has a long way to go, and it may be a while before we see its widespread application.

NEW DELHI: The reported move to terminate the services of Tata Consultancy Services Ltd employees found its echo in Rajya Sabha today with CPI(M) alleging that aged staffers were being sacked and new ones being hired at lower salaries. Demanding the intervention of the government, K N Balagopal (CPI-M) claimed thousands of employees have been thrown out in the TCS and it seemed there was no grievance redressal mechanism for them in the IT sector. "Employees face a bleak future. This is not only in TCS. This is not only in IT," he said adding that this was being done by "all new-generation employers". Responding to the Opposition concerns, Law Minister Sadananda Gowda promised to look into the issue. Balagopal said even after the District Labour Office of Tiruchi issued a notice to the company on the matter, no one from TCS appeared. His party colleague P Rajeeve said, "this is a new trend. They terminate people with ten-year experience and recruit new ones in their place to pay low salary." Another CPI-M leader Tapan Kumar Sen said this was happening in TCS even as the company earned the highest growth among all IT companies. "This kind of retrenchment is happening on a 'last come, first go' basis... Do not promote these things in the name of promoting ease of business," Sen said seeking the government's intervention into the matter. As members raised concerns, Deputy Chairman P J Kurien asked "are these companies exempt" from rules and shared the concern of the members. At this, Law Minister Gowda said,"I have taken note of it. I will look into it."

Over five billion downloaded Android apps are vulnerable to being hacked, cybersecurity researchers have found, as attackers exploit flaws in Google's operating system.Some 96 percent of malware -- or malicious software -- employed by hackers target Google Android, according to U.S. firm FireEye, which analysed more than 7 million mobile apps on Android and Apple iOS between January and October 2014.Apps designed to steal financial data were especially popular, the researchers found. The open-source nature of Android allows hackers to find the code behind a popular app, they said, and recreate the app almost identically but with a malicious code to infect users....Read More

The smartphone is ubiquitous, addictive and transformative.THE dawn of the planet of the smartphones came in January 2007, when Steve Jobs, Apple's chief executive, in front of a rapt audience of Apple acolytes, brandished a slab of plastic, metal and silicon not much bigger than a Kit Kat. "This will change everything," he promised. For once there was no hyperbole. Just eight years later Apple's iPhone exemplifies the early 21st century's defining technology.Smartphones matter partly because of their ubiquity. They have become the fastest-selling gadgets in history, outstripping the growth of the simple mobile phones that preceded them. They outsell personal computers four to one. Today about half the adult population owns a smartphone; by 2020, 80% will....Read More

Java and the JVM have been around a long time. Cast your mind back to 1995 – the year the net went private and the American started surfing the ‘net with AOL. In other significant tech events, it was also the year that Java – in its very earliest beta incarnation – first came into being. Whilst AOL’s time in the sun has been and gone (I’m just going to put this video here, to help transport you back to those glorious days of dial up), Java is as strong as ever – even if it may have lost some of its lustre amidst all those other JVM interlopers that sprung up, Gremlin-like, from the platform.In fact, given how long some programmers have been using the platform, there are, RebelLabs write, “many things that Java developers take for granted.” Whilst Java continues to straddle the top rungs of most leading language indexes, familiarity has served to breed a good deal of contempt over the past twenty years (sometimes deservedly so, admittedly). But in the midst of all the nay-saying, it can be easy to ignore all the great things about Java and the JVM....Read More

Google paid $25 million to get exclusive rights to the .app TLD, according to a new report. TLDs, or “top-level domains” are the bits like “.com” and “.net” at the end of web domains. ICANN, the organization responsible for managing web addresses, has been launching many new, customized TLDs in recent months.The purchase means that Google will be able to create web addresses like “google.app” or “android.app.” Google, of course, has its own domain registry where users can buy their own web addresses. The .app TLD may become available through that route, though Google hasn’t confirmed those plans....Read More

Without a doubt, jQuery has given a much needed boost to JavaScript, a language so useful but equally underrated at times. Before jQuery comes into picture, we used to write lengthy JavaScript code not just for bigger but even for smaller functionality. Those code were at times both difficult to read and maintain. Having written JavaScript before using this excellent library, I realized true power of jQuery, just after using it for a month. Given it's huge popularity, jQuery interview questions are increasingly asked in any web developer interview, not just beginners but also experienced developers, including HTML and JavaScript. Since jQuery is relatively new, most interview questions are asked from core jQuery library including selectors, DOM manipulation and jQuery basics. In this article, I am sharing a list of 16 jQuery questions asked to HTML and JavaScript programmers in different interviews....Read More

Although the point of this column is to discuss “where the rubber meets the road” of software development rather than theory, if you read SD Times, you are most likely managing a software development team or teams. As endlessly challenging as code is, dealing with people is, by far, the harder part of developing software products. Once upon a time, I had a certification for Project Management from some Very Prestigious Project Management Organization. I knew all about PERT and Gantt charts, critical paths, and resource balancing. I won’t say that knowledge of such things is useless in software project management, but they are not nearly as important as these five issues....Read More
